Sterically congested glycosides, glycosyl-β-(1→4)-glycosides, were stereoselectively synthesized by reduction of glycosidic spiro-orthoesters with LiAlH 4AlCl 3. This novel transformation is especially valuable when it is applied to the preparation of mannosyl-β-(1→4)-glycoside which must be one of the most difficult tasks in carbohydrate chemistry. |
